Dental Equipment

Digital Impressioning
(Highly Recommended) and CAD/CAM
(Good Idea based on Scope)
Perhaps the most revolutionary change in dentistry in recent years is the
development of digital impressioning techniques which use scanners.
Until recently a tooth or mouth impression required having a tray of goopy
alginate or unpleasant-tasting vinyl polysiloxane inserted in the patient's
mouth and held there until the material set. If there's an error or part of
the impression isn't sufficiently detailed, the whole process is repeated.
The impression is then decontaminated, poured into stone, and/or
shipped to a lab where a crown, denture, or other prosthetic tooth replacement is constructed. Impression
material is expensive, the use is time-consuming, the patient experience is not particularly pleasant, and
patients frequently must return for multiple appointments. Today, those same impressions can be taken more
accurately, quickly, pleasantly and with improved clinical results by using digital scanners.
The head of the scanner is an approximately tooth brush-sized wand which is covered by an infection control
barrier sleeve. There are essentially two types of scanners. One type uses blue LED (light-emitting diode). These
systems are optical scanners and they require a contrasting medium or powder to acquire a representation of
the tooth morphology. This means that a fine powder is sprayed over the mouth area to be scanned to assure
accurate imaging. There are also systems that use laser technology to scan and measure distances from the
tooth surface to acquire the image. These systems do not require powder.
The scanned image becomes part of a digital record which can be
either sent electronically to a lab along with instructions, or used to mill
a restoration in-house and even same day. Digital scanners eliminate
gingival retraction of the tooth to be restored, tray selection, material
dispensing, disinfection, disposal of biohazard, disinfection of the
impression tools, pouring models, model trimming, hand writing the
lab script, packaging the impression for shipping to the lab, distortion,
and retakes.
Some scanners are well-suited to the accuracy needed for crown and
bridge restorations; but there is at least one scanner, 3Shape, which
can accurately scan full arches for partial and full dentures.
A complete CAD/CAM system takes you from digital impressioning all the way through tooth restoration with
a milling unit. Restorations can be produced in an hour or at least same day for patients who cannot take
additional time off work to return for placement of a crown or onlay. The software which guides the creation
of the restoration is accurate, intuitive, and easily learned by a dental assistant. For programs expanding
their services that want and need a fast, desirable outcome, adopting a complete CAD/CAM solution can be a
valuable addition to the quality and choices of treatment.
Digital impressioning and CAD/CAM solutions are significant investments, but may be solutions for which
writing a specific grant request is warranted.
